Abstract
In the previous chapter we arrived at a design for an E.S.R. spectrometer (Fig. 1.4) by considering how the instrumentation of some of the previously developed branches of spectroscopy can be modified to suit the particular frequency range and application of E.S.R. Here we shall discuss some of the methods whereby this and similar arrangements can be used to trace out spectra. Then from the Bloch model of magnetic resonance we shall develop a circuit model for the microwave system, and from this shall derive an improved arrangement. Finally, some modifications to the improved system will be suggested in the light of considerations of detector sensitivity and the need to discriminate between the absortion and dispersion components of the E.S.R. signal.
